It depends on the cut scene. If it's from an in-game event, its once per event so you'd have to wait for the event again. If it's from a Flashpoint for example replaying the flashpoint will allow you to see the cutscene again. Same goes with the chapters for Fallen Empire, Eternal Throne, etc. If you replay the chapter, any cutscenes in that chapter are able to be viewed again.
Outside of that, there is no way to replay cutscenes.
Hey, just be happy it works! The patch has made my machine incompatible for the game!
